Gastrodia elata is indeed effective in treating certain types of dizziness and vertigo, and is particularly suitable for vertigo caused by excessive liver fire or hyperactive liver yang (such as hypertension accompanied by a sensation of fullness in the head and headaches). However, it is important to note that Tianma is not effective for all types of dizziness; it primarily targets conditions classified in Traditional Chinese Medicine (TCM) as “internal liver wind” or “phlegm-dampness disturbing the upper body.”
I. Why Does Gastrodia elata Treat Dizziness?
Calms the Liver and Subdues Wind, Subdues Yang and Stops Dizziness: Gastrodia elata has a sweet and neutral nature and enters the Liver meridian, specifically regulating excessively hyperactive “Liver Yang.” For symptoms such as a sensation of heaviness in the head, headaches, and a spinning sensation caused by emotional agitation, high stress, or hypertension, it can help calm and soothe the body.
Resolving phlegm and unblocking meridians to improve cerebral blood supply: For dizziness caused by phlegm-dampness obstructing the meridians (often accompanied by a heavy sensation in the head, chest tightness, and nausea), Gastrodia elata can resolve phlegm and unblock the meridians. Modern research has also found that Tianma dilates blood vessels and improves microcirculation, thereby alleviating vertigo.
II. How to Use Gastrodia elata According to Symptoms
Hypertension with dizziness: This is the most classic indication for Gastrodia elata. You can boil Gastrodia elata slices in water and use the liquid to steam eggs, or grind it into a powder and take a small amount orally to help relieve a sensation of head heaviness and headaches.
Dizziness due to phlegm-dampness: Characterized by dizziness accompanied by a heavy sensation in the head, nausea, and chest tightness. Gastrodia elata can be boiled and eaten with tofu, or used in combination with herbs that strengthen the spleen and resolve dampness, such as Bai Zhu and Fu Ling.
III. Precautions for Using Gastrodia elata
Must Be Used for the Correct Condition: Gastrodia elata is primarily intended for vertigo caused by “excess patterns.” If dizziness is caused by deficiency of qi and blood (such as pale complexion, fatigue, or symptoms worsening after exertion), Gastrodia elata should not be used alone.
Dosage Control and Contraindications: Avoid cold and greasy foods while taking this herb. If you experience chills, abnormal heart rate, a significant drop in blood pressure, or allergic symptoms such as a rash, stop taking it immediately and seek medical attention.
Special Populations: Follow Medical Advice: Pregnant women, breastfeeding women, children, the elderly or frail, and patients with underlying conditions such as hypertension, heart disease, liver disease, or diabetes must consult a doctor before use. If symptoms do not improve after 7 consecutive days of use, seek medical attention promptly.
